Abstract:
The antihistamines are drugs who compete for the histamine receptor H-1, blocking the liberation of autacoid mediators, that is the reason for their action in allergic diseases. It's important to know the pharmacodynamics and pharmacokinetics of these drugs in order to choose the best one for the patient, looking for the ones who have less side effects and work better. We show a summary of the principal antihistamines, their actions and side effects.
